Ancient Shangzhai people consumed broomcorn millet, the meat of terrestrial non-ruminants and wild ruminants, and dairy of wild ruminants during the Middle to Late Neolithic Age (7500–6000 yr BP) of Beijing.

As the crossroads of prehistoric cultures, the Beijing region is an important area for studying the exchange of prehistoric culture and the spread of millet agriculture, while there is a gap of approximately 2,000 years between millet remains founded in the Neolithic sites (the early Donghulin site and the late Shangzhai site). The Shangzhai site is located in the Pinggu Basin in eastern Beijing (Figure 1), and it has a large time span with sequential strata; however, there are few macro animals and plant remains found at this site, thus the subsistence strategy of ancient people remains unclear.
For this reason, the absorbed lipids of pottery sherds unearthed in the Neolithic cultural layer of the Shangzhai site were extracted and analysed by gas chromatography-mass spectrometry (GC-MS) and gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS).
The results show that these potteries were used to process millet, the meat of terrestrial non-ruminants and wild ruminants, and dairy of wild ruminants (Figures 2 and 3), providing new insights for the subsistence strategy and the development of millet agriculture in the Middle and Late Neolithic Age of Beijing. In addition, the food processing in pottery may be an internal heating method, such as stone boiling.
It remains to be verified whether there is a continuation of dry-land agriculture between the Donghulin site and Shangzhai site, and the cultivation of millet in Shangzhai may have been influenced by the Zhaobaogou culture in the North.
